3 Solving Polynomial Equations We have spent much time on learning how to factor polynomials. Now we will look at one important use of factoring. In this section, we will use factoring to solve equations of degree 2. Up to this point, we have only looked at solving equations of degree one.
10 Solving Polynomial Equations Solving a Quadratic Equation by Factoring 1) If necessary, rewrite the equation in the standard form, moving all terms to one side, thereby obtaining zero on the other side. 2) Factor. 3) Apply the zero-product principle, setting each factor equal to zero. 4) Solve the equations formed in step 3. 5) Check the solutions in the original equation.
